In this work, we evaluated relationship between specific contact resistance and sensitivity of pH sensor by changing the ohmic contact metallization consisted of source and drain. The sample was fabricated for analysis of electrical characteristics [...]

Polymer/Boron Nitride (BN) nanocomposite is promising interfacial material for cooling of electronic systems. It is important to determine percolation threshold when it practically uses in the industry. But, the exact prediction with existing model is [...]

In this presentation, a monolayer of silver nanoplate is introduced as an epitaxial template and doping source for vertically aligned p-type ZnO nanorods. Silver nanoplates were synthesized through room temperature polyol process and the monolayer [...]

SWCNTs have various bandgaps so that they show metal as well as semiconductor characteristic. However, it is difficult to separate the metallic and the semi-conducting SWCNTs. Also, the high contact resistance at the interface between [...]

We fabricated high efficiency organic-quantum dot hybrid solar cells. By employing the hybrid active layer, which absorbed the light in wide range, the short circuit current (Jsc) is increased due to a multiple exciton generation [...]

This study describes the development of multifunctional nanofiber scaffolds consisting of multiple layers of nanofiber scaffolds and nanofiber-incorporated PEG hydrogels. We fabricated double-layered nanofiber scaffolds that were micropatterned with PEG hydrogels by combining two-step sequential [...]

The present work reports ammonia (NH3) gas sensing properties of Graphene film synthesized by chemical vapor deposition (CVD) in ambient condition. Graphene with a large area is synthesized on Cu foils by chemical vapor deposition [...]

Radon is classified as the second leading cause of lung cancer in the US. There have been plenty of trials to mitigate indoor radon gas which penetrated through the floor cracks, building materials and groundwater [...]
